Used in organic semiconductor materials due to its conjugated aromatic structure, enabling application in thin-film transistors and optoelectronic devices. Serves as an intermediate in the synthesis of liquid crystals and pharmaceuticals, particularly in reactions requiring iodinated biaryl scaffolds for cross-coupling processes. Its high molecular rigidity and polarizability support use in photovoltaic systems and as a dopant in emissive layers of OLEDs. Also employed in radiolabeling studies, leveraging the iodine atom for tracking in biochemical assays.
